2.2 Main structure principles: Lifting mechanism: Each column is installed

with a hydraulic cylinder, when hydraulic oil is pressed from power pack into the lower chamber of main cylinder, piston rod moves upwards to drive the upward movement of carriage through leaf chain.

Load supporting mechanism:When vehicle drives into the working area, adjust the angle and telescopic length of arms to make lifting pads at an effective load supporting position that contact with vehicle, and then adjust the lower screw’s height of lifting pad to make it applicable for vehicles with different chassis.

Balance mechanism:In order to keep machine balanced during lifting and lowering, two carriages are interconnected and forced to move synchronously by two wire ropes. If the right and left carriages and arms are not at the same level, adjust the end nut of wire rope and pull wire ropes tight to make arms leveled.

Manual safety locking mechanism: the safety locking plates are installed on the two carriages and the toothed bar plate is welded

on the internal wall of the column. During the lifting of the carriage, the safety locking plate goes up against on the toothed bar plate under the tension of spring. When the carriage stops, the safety locking plate opens and then is engaged in the toothed bar slot to ensure the carriage will not go down; when the lowering operation is required, just raise the carriage upward a little to loosen the safety locking plate from the toothed bar slot, and then manually pull the steel wire rope to let sliding plate lift up the safety locking plate so that the safety locking is released, the carriage can be lowered down. Because the manual safety locking device are installed on the two carriages, double safety protection is provided; therefore, to disengage the safety locking, the steel rope on the two carriages shall be respectively pulled. To prevent the vehicle from slipping off, the swing arm assembly employs positioning mechanism, makes the swing arm capable of automatic locking during operation.

Safety lock scope: Safety lock mechanism is effective when the front end of carriage is between 450mm and 1900mm high above the ground.

3 Operation Descriptions 3.1 Precautions for vehicle repair

work Different vehicles have different center of gravity

positions. First understand the position of center of gravity, and when the vehicle enters into the lift, make its center of gravity close to the plane formed by two columns. Adjust the swing arm, and make the lifting pad support onto the lifting point of the vehicle.

For vehicle lift with top beam, pay attention to the car roof position observation in order to avoid accident during lifting.

Carefully read the warming symbol. The hydraulic valves have been adjusted before

ex-factory, and the user can’t make self-adjustment, otherwise it will be responsible for all the consequences generated.

Based on the production needs, some specifications in the instruction manual are subject to change without notice.

3.2 Preparation before Operation

Lubricate contact surface of the carriage with general-purpose lithium grease(GB7324-87). All sliding surface should be coated evenly from the top to bottom.

Fill hydraulic oil N32 or N46 to the oil reservoir of the power unit.

3.3 Inspection before operation Check to see if the motor power is installed properly. Check to see if all the connection bolts are fastened.

Note: Don’t operate the lift with damaged cables or damaged and missing part, until it is inspected and repaired by the professionals.

3.4 Lifting the Vehicle

Keep work area clean; don’t operate the lift in cluttered work area.

Lower the carriage to the lowest position. Reduce the swing arm to the minimum length. Swing the arm along the route of the vehicle Move the vehicle to the location between the two

columns Swing the arm and put the lifting pad below the

recommended lifting point, and adjust the height of lifting pad to touch lifting point of vehicle

Press the UP button on the electric control box, slowly lift the vehicle to ensure the load balance, and then raise the lift to the required height.

Release the UP button. Press the DOWN button to engage the safety

lock of carriage. At this time, the vehicle can be repaired.

Note: Before operation, the safety locking devices

must be Inspected.1) The gear blocks of the arm end must engage the gear block of the restraint shaft.2) No broken strand in the steel cable. 3) No deformation in the arm pad.

When lifting the vehicle, all the swing arms must be used.

Before lifting the vehicle, check all the hydraulic hose and fittings for oil leakage. In case of leakage, please don’t use the lift. Remove the fitting with leakage and re-seal. Re-install the fitting and check if oil leakage still exists.

After the vehicle is lifted, when adding or removing any major heavy object, use jack stand to maintain the balance of the vehicle.

3.5 Lowering the Vehicle

Clean the work area before lowering the vehicle. First press the start button to raise the vehicle a little, and then pull two steel ropes on two carriages to disengage the safety lock.

Press the lowering handle to lower the vehicle. Lower the vehicle till the swing arm down to the bottom and the lifting pads leave the vehicle chassis, and then release the lowering handle.

The swing arms under the vehicle must be fully shrunk

Note: When the lift doesn’t work, you must switch off the power.

The working principle of the hydraulic system is as follows:

As shown in Fig.4a, when the start button is pressed, the

motor 2 is activated, driving the oil pump 1, sucking the

hydraulic oil from the oil tank into the oil cylinder 9, forcing

the piston rod move. At this time, the safety valve 5 is

closed. (The max working pressure is already adjusted

before ex-factory. The safety valve can ensure the capacity

of the rated load, but when the pressure in the system

exceeds the limit, automatic overflow will happen inside

safety valve to protect the hydraulic system). Release the

start button to stop the oil supply and the lifting will stop.

For lowering, first start Motor 2 to raise vehicle a little, pull

the steel ropes on two carriages to release the safety lock

mechanism, then press the lowering handle, the valve 6 is

actuated, the hydraulic oil flows back and the lift starts

lowering.

to keep it clean. Before cleaning, first switch off the power to ensure the safety.

The working environment of this unit should be clean. In case of dust in the working environment, it will speed up the parts wearing and shorten the service life of the lift.

Every day: Before the operation, carefully check the safety

mechanism of the lift to ensure the electromagnet suction and release action is proper, and the safety plate is in good condition. When finding any abnormal situation, make adjustment, repair or replacement immediately.

Check to see if the steel cable connection is proper, and if the tension is at the optimum status.

Check to see if the connection between hydraulic cylinder and carriage is proper, if the connecting nut between the steel chain and carriage is loose or falling. Refer to Fig.6

Fig.6

Every month: Retighten the anchor bolts.

Lubricate chains/cables. Check all the chain connectors, bolts and pins to

ensure correct installation Check all the hydraulic lines for wearing Check to see if the carriage and the inner side of the

column are properly lubricated. Use high-quality heavy lubrication grease (lithium based lubrication grease GB7324-87).

Note: All the anchor bolts should be tightened

completely. If any screw doesn’t function for some reason, the lift can not be used until the bolt is replaced Every six months:

Check all the movable parts for possible wearing, interference or damage.

Check the lubrication of all the pulleys. If the pulley has dragging during the lifting and lowering, add appropriate lubricant to the wheel axle.

When necessary, check and adjust the balancing tension to ensure the horizontal lifting and lowering.

Check the verticality of the column.

Note: The inner corner of each column should

be lubricated with lubricant, to minimize the roller friction and ensure the smooth and even lifting.

Maintenance of hydraulic system: Clean and oil change

In the six months after initial use of this unit, clean the hydraulic oil tank and replace the oil, later clean the hydraulic system once a year, and replace the oil. See Fig. 7

Replace the seal After this unit is put into operation for certain period, if finding the oil leakage, carefully check it; if the leakage is due to the wearing of sealing materials, immediately replace the worn one based on the original spec. See Fig. 7

Tool Model Leveling instrument Carpentry type Chalk line Min 4.5m Hammer 1.5kg Medium crescent wrench 40mm Open-end wrench set 11mm-23mm Ratchet socket set Flat Screw driver 150mm Rotary hammer drill 20mm Concrete drill-bit ¢19mm

9. Unpacking

Open the packing box; remove the packing materials and inspect the lift for any sign of shipment damage. Check by packing list to see if the main parts and accessories are complete. Keep the packing materials away from the children to avoid danger; if the packing materials cause the pollution, they shall be treated properly.

10. Installation

10.1 Important notice The wrong installation will cause the lift damage or

personal injury. The manufacturer will not undertake any responsibilities for any damage caused due to incorrect installation and usage of this equipment, whether directly or indirectly.

The correct installation location shall be “horizontal” floor to ensure the horizontal lifting. The slightly slope floor can be corrected by proper shimming. Any big slope will affect the height of the lifting pad when at the bottom or the horizontal lifting. If the floor is of questionable slope, consider a visual inspection, or

pour a new horizontal concrete slab if possible. In short, under the optimum horizontal lifting status, the level of the lifting relies on the level of the floor where it is installed. Don’t expect to compensate for the serious slope.

Don’t install the lift on any asphalt surface or any surface other than concrete. The lift must be installed on concrete floor conforming to the minimum requirement showed in this manual. Don’t install the lift on the concrete with seams or crack and defect. Please check together with the architect.

Without the written approval of the architect, don’t install the lift on a second floor with basement.

Overhead obstruction: The lift installation area can’t have any overhead obstruction, such as heater, building support, electrical pipe, etc.

Concrete drilling test: The installation personnel can test the concrete thickness at each site by drilling test. If several lifts are installed at one place, it is preferred to make drilling test in each site.

Power supply: Get ready the power supply before the installation. All the electric wiring and connecting should be performed by a certified electrician.

10.2 Installation Procedure

10.2.1 Selecting installation site

Selecting installation site based on the following conditions: Lift can only be installed on concrete slab, which

must have a minimum thickness of 250mm and should be aged 7days at least.

The concrete slab shall have reinforcement by steel bar.

The concrete slab must be leveled. If the thickness of the whole ground concrete is

greater than 250mm, the lift can be installed directly Check the possible obstruction, e.g. low ceiling, top

pipeline, working area, passage, exit, etc. The front and back of the lift should be reserved with

sufficient space to accommodate all the vehicles (Fig. 8).(evaluating from the center line ,each edge should be about 4m)

For floor-plate two post lift, use lifting equipment to place power side column upper right to the location. Align the base plate of column with the chalk line layout. Guided by holes on the base plate of the

column, use 5 concrete anchor bolts to fix it onto the ground. Drill and install anchor Bolt s at one time, during the drilling process, ensure no movement of the column.(Fig.11b) .

Fig.11b

Note: ♦ Use sharp Φ19mm concrete drill-bit to drill the

holes so as not to drill the hole too large, Use proper pneumatic tool to remove the dust from the hole. The depth of the hole is the same as that of the anchor bolt. Insert the anchor bolt and make the washers lean against the base of the column.

♦ Only use torque wrench instead of impact tools to fasten anchor bolts.

♦ Insert proper steel shim under the base seat of column to plumb the column.

Note: The thickness of shims shouldn’t exceed

5mm. To get the correct and safety installation, please follow the following installation steps. Wear the safety goggles Use hard alloy drill-bit. Don’t use the drill-bit with wearing exceeding the

tolerance. The drill and concrete surface should be kept

perpendicular. Let the drill work itself. Don’t apply the extra force,

and don’t ream the hole or allow the drill to wobble. The drilling depth of hole is based on the length of

anchor bolt .The distance from the Bolt head to the concrete floor should be more than twice of the bolt diameter.

Remove the dust from the hole. Gently tap the bolt into the hole till the washer rests

against the base plate of column. Fasten bolts

10.2.4 Install the floor plate, top beam
